1 Claim.

This invention appertains to new and useful improvements in liquid and gaseous fuel burners and more particularly to a burner which has as its principal object the elimination of wicks, perforated shells, and various other attachments which complicate present day types of burners such as are used in kitchen ranges, auxiliary heating stoves, and circulating heaters.

Another important object of the present invention is to provide a burner which will start up and produce maximum heat quickly.

Another important object of the present invention is to provide a burner ofthe type specified which can be readily taken apart for the purpose of cleaning, repair and replacement of parts.

These and various other important objects of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 is a fragmentary longitudinal sectional view through the burner, taken substantially on line I-I of Figure 2.

Figure 2 is a fragmentary top plan view showing the burner.

Figure 3 is a fragmentary top plan View showing the preferred form of the base.

Figure 4 is a vertical sectional view taken substantially on line 4-4 of-Figure 2.

Figure 5 is a top plan View of the baille plate.

Figure 6 is a fragmentary top plan view of another form of base.

Figure '7 is a sectional View taken substantially on line 'I-l of Figure 6.

Figure 8 is a cross sectional view taken substantially on line 8-8 of Figure 6.

Referring .to the drawings wherein like numerals designate like parts, it can be seen in Figure 1 that numeral 5 represents the stove base which is provided with hollow raised side walls 6 and a sunken top wall I having a fuel discharge opening 8 adjacent the end wall of the base opposite from the fuel entrance at the mixing chamber 9. The bottom of the base 5 is provided with a grooved shoulder IB lin which an electrical heating element II is placed for heating the contents of the base 5.

Upon the top 1 of the base and within the confines of the hollow wall B is placed the upwardly tapering frame l2 which supports the baille plate I3, the latter being provided with a pair of parallel longitudinally extending fuel emitting slots I 4 therein. Upon this baille plate I3 is imposed the cover or dome I5 carrying the burner tips I6 which are constructed of lava or some other similar material.

By referring to Figures 1 and 4, it can be seen that the end wall of the base 5 opposite from the mixing chamber 9 is provided with an inwardly tapering deflector Il which serves to deflect the fuel vapor into the portion of the hollow base underlying the opening 8 so that the same will pass upwardly through the opening l8 and be guided upwardly toward the burner tips I6 by the slots Ill- I4 in the baille plate I3.

Numeral I8 represents the fuel supply line to the mixing chamber 9 for carrying fuel to this chamber, while numeral I9 represents a casing having the blower 28 mounted therein for blowing air through the spout 2I to the mixing chamber 9. The fuel and air mixes in the chamber 9 and is spread by the deecting block 22 at the adjacent end of the base 5 so as to pass along the l5 side walls of the base at the inner side thereof. In this passage of the fuel, the fuel passes over the heating element .II and becomes thoroughly heated and vaporized before it rises through the opening 8 to reach the burner tips I6.

The blower housing I9 isprovided with the usual air inlet opening 23 which is provided with an adjustable cover 24 whereby the draft can be regulated.

A slightly modified form of the invention is shown in Figures 6, '7, and 8, wherein the mixing chamber 8a has a spreader block 22a which serves to deflect the partly vaporized fuel into the side passageways 25-2 5, above the lateral portions of the heating element IIa, wherein the fuel is thoroughly heated and vaporized. The fuel in passing toward the opposite end of the base 5a is deflected inwardly through the opening 26 in the opposite end of the base from the spreader block 22a, behind the V-shaped deflector I'la and from there the vaporized fuel rises through the deilector plate I3 to the burner tips (not shown in Figures 6, 7, and 8).

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size, and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

What is claimed is:

In combination, an elongated burner base having a pair of passageways extending along the sides thereof, a mixing chamber in one end of the base, a fuel spreader for deflecting the fuel toward the said passageways, a chamber at the intermediate portion of the base communicating with the passageways at the end of the base opposite from the spreader, a burner tip supporting dome over the said chamber, and means for deflecting the fuel passing through the said passageways into the said chamber.
